C10D.3 We can prove that the dot product is distributive as follows. Let šw +. Note that we can think of the dot product υ-s as being li l times the projection of s on u. The figure below shows this projection as well as the projec- tions of w and q on 11. (a) Assume that a, q, and 11 all lie in the same plane. Use the diagram above and a trigonometric identity to (b) Assume that š...

Suppose the tractor pulls horizontally on the sled instead of at an angle of 36.9. As a result, the magnitude of the friction force increases to 4400N. What is the total work done on the sled? Answer: 1.20x10 J onedo 72 Work 187 SOLUTION The statement of the problem gives the hright h rather than the distance s measured along the ramp, but we can solve for h by recogsizing from the geometry in Figare 7.13 that s sinB- h....

python 3 inheritance
Define a class named bidict (bidirectional dict) derived from
the dict class; in addition to being a regular dictionary (using
inheritance), it also defines an auxiliary/attribute dictionary
that uses the bidict’s values as keys, associated to a set of the
bidict’s keys (the keys associated with that value). Remember that
multiple keys can associate to the same value, which is why we use
a set: since keys are hashable (hashable = immutable) we can store
them in...

BOX 5.1 The Polar Coordinate Basis Consider ordinary polar coordinates r and 0 (see figure 5.3). Note that the distance between two points with the same r coordinate but separated by an infinitesimal step do in 0 is r do (by the definition of angle). So there are (at least) two ways to define a basis vector for the direction (which we define to be tangent to the r = constant curve): (1) we could define a basis vector es...

Exploration 16.2:A Parameterization of Movement in the Plane Since you are approximating the various chosen s lengths, it might be helpful to note that 1/8 of an inch is equal to 0.125 inches and thus 1/16 of an inch is approximately equal to Often it is useful to investigate a rule or relation between ordered pairs in the plane as they relate to yet a third variable or parameter. In this investigation, movement of an object in the plane is...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
